摘要： A toy that tests the skill of a user in performing a function is described which relies for operation on the interaction of various substances having different specific gravities. A tubular container is provided for supporting a column of a liquid such as water, and a syringe-type squeeze bulb communicates with the bottom of the container to enable introduction of controlled amounts of air into the bottom of the column. A capsule is also provided having a greater specific gravity than the liquid in the container so that the same will normally sink through the liquid in the container. The capsule includes a chamber for capturing air which has been introduced into the container. Since air is a gas and has a lower specific gravity than the liquid, it will tend to rise within the column. By controlling the amount of air introduced into the liquid for capture by the capsule, a user of the toy can control the movement of the capsule. That is, the user can slow the descent of the capsule by introducing a small amount of air, suspend the capsule at a prescribed location within the liquid by introducing a specific greater amount of air, and reverse the direction of the capsule by introducing more air.

摘要： A DISPLAY DEVICE FOR CUT FLOWERS IS PREPARED BY INJECTING AN AQUEOUS SOLUTION OF UREA-FORMALDEHYDE PRECONDENSATE CONTAINING ABOUT 40% BY WEIIGHT OF SOLIDS, A SMALL AMOUNT OF PHOSPHORIC ACID AS A CATALYST, AND A FOAM-STABILIZING SURRFACTANT, WITH COMPRESSED AIR INTO AN OPEN POLYETHYLENE BAG, AND HEAT-SEALING THE OPEN SIDE OF THE BAG BEFORE THE WATER COULD EVAPORATE FROM THE FOAM WHICH GRADUALLY SOLIDIFIES. WHEN SMALL HOLES ARE PUNCHED IN THE BAG AND THE STEMS OF FLOWERS ARE INSERTED, THE FLOWERS ARE KEPT FRESH.
